OPERATING INSTRUCTIONS

HOLDING THE UNIT

WARNING:

reduce the risk of injury when operating this unit.

Before operating the unit, stand in the operating position (Fig. 10). Check for the following:

• The operator is wearing eye protection and proper clothing

• With a slightly-bent right arm, the operator’s hand is holding the shaft grip

• The operator’s left arm is straight, the left hand holding the D-handle

• The unit is at waist level

• The cutting head is parallel to the ground and easily contacts the grass without the need to bend over

ach time the head is bumped, about 1 inch (25.4 mm) of trimming line releases. A blade in the

E cutting head shield will cut the line to the proper length if any excess line is released.

For best results, tap the bump knob on bare ground or hard soil. If attempting a line release in tall grass, the engine may stall. Always keep the trimming line fully extended. Line release becomes more difficult when the cutting line gets shorter.

ig. 11

NOTE:Do not rest the Bump Head™ on the ground while the unit is running.

Some line breakage will occur from:

• Entanglement with foreign matter

• Normal line fatigue

• Attempting to cut thick, stalky weeds

• Forcing the line into objects such as walls or fence posts

TIPS FOR BEST TRIMMING RESULTS

• Keep the cutting head parallel to the ground. Do not force the cutting head. Allow the tip of the line to do the cutting, especially along walls. Cutting with more than the tip will

• reduce cutting efficiency and may overload the engine.

• Cut grass over 8 inches (200 mm) by working from top to bottom in small increments to avoid premature line wear or engine drag.

• Cut from right to left whenever possible. Cutting to the left improves the unit's cutting efficiency. Clippings are thrown away from the operator.

Slowly move the unit into and out of the cutting area at the desired height. Move either in a forward-backward or side-to-side

•

otion. Cutting shorter lengths produces the best results.

• Trim only when grass and weeds are dry.

• The life of the cutting line is dependent upon:

Following the trimming techniques

•

• What vegetation is being cut

• Where vegetation is cut

For example, the line will wear faster when trimming against a foundation wall as opposed to trimming around a tree.

ECORATIVE TRIMMING

ecorative trimming is accomplished by removing all vegetation around trees, posts, fences, etc..

otate the whole unit so that the cutting head is at a 30° angle to the ground (Fig. 12).
